Ubuntu 12.04LTS shipped with SqueezeLite 1.3 and systems that were updated to 14.04LTS got stuck on 1.3. Unfortunately SqueezeLite 1.3 is not compatible with 14.04LTS and will cause excessive processor load if not updated.
As usual please run the updater to update your system and to install any other pending Ubuntu updates too;
Dianemo X86 will stay on SqueezeLite 1.3 as this is the final release from Canonical for that release of the OS. However if you'd like to have a try building your own SqueezeLite 1.8 package for Dianemo X86 12.04LTS then be our guest - see below. However on 12.04LTS I should point out that as far as we can see there is absolutely no advantage in having 1.8 installed...which is why we have not built a 12.04LTS deb.
Note this is only if your still running Ubuntu 12.04LTS and have some spare time!!; If your feeling brave and want to try building SL 1.8, then you can get the code from our fork: https://code.google.com/r/raducx-squeezelite-ubuntu-deb/
dpkg-buildpackage -rfakeroot -b -us -uc
the code is vanilla 1.8 with Debian package stuff added on top;
...and fix the things that are complained about - keep doing that until it works ☺
...and then install the deb.
